Magnetic properties of different phases iron oxide nanoparticles prepared by micro emulsion-hydrothermal method.

In this study, we report the synthesis of iron oxide nanoparticles (FeONPs) using micro-emulsion-hydrothermal method. By adjusting the synthesis temperature, we successfully produced FeO nanorods and nanospheres. In addition, the 2-octanol, and the surfactant cetyltrimethylammonium bromide served as a solvent in the synthesis process.

5S Multifunctional Intelligent Coating with Superdurable, Superhydrophobic, Self-Monitoring, Self-Heating, and Self-Healing Properties for Existing Construction Application.

There is a constant drive to develop ultra-high-performance multifunctional coatings for existing construction used in modern engineering technologies. For these materials to be used in unsound infrastructure protections, they are required to present enhanced robustness while bearing functionalities to meet multiple uses. Single-function coating is not smart enough to provide satisfactory protection, and the preparation process of multifunctional materials is complex, costly, and provides poor durability.

A novel CWPO/HO/VUV synergistic treatment for the degradation of unsymmetrical dimethylhydrazine in wastewater.

In this paper, the catalytic wet peroxide oxidation (CWPO) combined with vacuum ultraviolet (VUV) irradiation was developed to mineralize the wastewater with high concentration of unsymmetrical dimethylhydrazine (UDMH), especially to decompose the main byproduct of UDMH decomposition, N-nitrosodimethylamine (NDMA). CuO-NiO-MgO/γ-AlO was used as the catalyst and HO as the resources of . Fourier Transform Infrared spectroscopy (FT-IR), X-ray Powder Diffraction (XRD), Scanning Electron Microscopy (SEM) and Energy-Dispersive X-ray spectroscopy (EDX) were employed to evaluate the structure of the catalyst.

Electrocatalytic Behavior of Hemoglobin Oxidation of Hydrazine Based on ZnO Nano-rods with Carbon Nanofiber Modified Electrode.

A novel biosensor was developed by immobilizing hemoglobin (Hb) on a glassy carbon electrode (GCE) modified with a composite of ZnO nano-rods and carbon nanofiber (CNF), a strong reducer, hydrazine, was firstly used to evaluate the electrochemical behavior of Hb on Hb/ZnO/CNF/GCE. UV-vis and circular dichroism (CD) spectra indicated the conformational structure of Hb interaction with ZnO/CNF was predominantly an α-helical structure. The modified electrodes were characterized by scanning electron microscopy (SEM), electron impedance spectroscopy (EIS), and cyclic voltammetry.

Preparation and characterization of monodispersed microfloccules of TiO₂ nanoparticles with immobilized multienzymes.

Microfloccules of TiO(2) nanoparticles, on which glycerol-dehydrogenase (GDH), 1,3-propanediol-oxidoreductase (PDOR), and glycerol-dehydratase (GDHt) were coimmobilized, were prepared by adsorption-flocculation with polyacrylamide (PAM). The catalytic activity of immobilized enzyme in the glycerol redox reaction system, the enzyme leakage, stabilities of pH and temperature, as well as catalytic kinetics of immobilized enzymes relative to the free enzymes were evaluated. Enzyme loading on the microfloccules as much as 104.

1-[(Butyl-amino)(phen-yl)meth-yl]naphthalen-2-ol.

In the title compound, C(21)H(23)NO, obtained via a one-pot synthesis, an intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation. The dihedral angle between the fused ring system and the phenyl ring is 78.27 (5)°.

Fabrication of nanofibrous inhaler device.

It has been proven that administration by inhalation is one of the alternative and effective approaches to dose biomedicines such as insulin for diabetics. Here, we introduce a new approach to fabricate the inhaler, posing the merits of not using volatile solvent, having selectable size of drug particles, and being simple and low cost compared with conventional devices. Creatine particles were prepared by spray-drying, and simultaneously a nanofiber mat of crosslinked poly(vinyl pyrrolidone) (PVP) was used to collect the graduated creatine nanoparticles.
